I have been running a Flint 2 MT6000 on my
Virgin Gig1 connection since they were released. It has been rock solid…..until now.
I flashed vanilla Openwrt on it last year and decided last week to upgrade from 24.10.6 to 25.12.4 and ever since I have been plagued with a weird packet loss problem which has left the connection unstable.
I have ran ping plotter, directly wired into the 2.5gb LAN1 port on the Flint and the packet loss appears to be coming from HOP 2, which I believe is my local Virgin CMTS. It’s sporadic and happens during the night too. It is causing buffering, making work from home difficult but without the packet loss, the connection is performing well still pulling over 1Gbps and the latency is good and the jitter is stable.
I don’t really like running the SH5 in router mode as my Openwrt configuration is highly customised with multiple VLANS etc but I put it in router mode this afternoon and the connection is rock solid. No packet loss at all. BQM looks stable.
Back into modem mode with the Flint, it’s dropping packets again. Red packet loss spikes and red dots across the top of the BQM.
I have tried rolling back to 24.10.6 with my config backed up. Tried a brand new fresh build. Tried GL-iNets firmware, 4.8.4 and the 4.9.0 beta. They’re all the same. No difference.
I have checked the logs on the Flint and it’s not giving me any clues at all. No disruption on the WAN port. It doesn’t appear to be flapping. I have tested my cat6 with a cable tester, it has passed.
I am stumped and apart from buying a replacement router, I’m not sure what to check next.
It could be the WAN port on the SH5 but the WAN port on the Flint 2 does not appear to be dropping.
Is there anything else I can check on the Flint 2 to see if the SH5 wan port is flapping or the disruption is being caused by the cable modem?
